True or false? in order to inscribe a circle in a triangle, the circle's center must be placed at the circumcenter of the triang
Dvinal [7]

Answer:

<h2>False.</h2>

Step-by-step explanation:

A inscribe circle in a triangle means to draw the biggest circle possible inside such triangle. To do that perfectly, we first have to find the incenter of the circle, which is the intersection of all three internal bisector of the triangle, that point is the center of the inscribed circle.

Therefore, the statement is false.

In addition, a circumcenter allow to perfectly draw a circumscribed circle, which is outside the triangle, which is not the case here.

The current population of Fun City is 21000 people. If the population of the city will double every 51 years then the population
Arisa [49]

Answer:

The population of Fun City after 171 years would be 214563.

Step-by-step explanation:

The statement depicts a case of exponential growth, whose model is described below:

p(t) = p_{o}\cdot r^{\frac{t}{T} } (1)

Where:

p_{o} - Initial population, no unit.

p(t) - Current population, no unit.

r - Growth rate, no unit.

t - Time, in years.

T - Growth period, in years.

If we know that p_{o} = 21000, r = 2, t = 171\,yr and T = 51\,yr, then the population of the city after 171 years is:

p(t) = 21000\cdot 2^{\frac{171}{51} }

p(t) = 214563

The population of Fun City after 171 years would be 214563.
